SPRAYING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 576,225, dated February2, 1897. Application filed July 31, 1896. Serial No. 601,158. (Nomodel.)

To all whom it may concern:

Be it known that l, JOSEPH H. POTTER, a citizen of the United States,residing at Batavia, in the countyof Genesee and State of New York, haveinvented a new and useful Improvement in Spraying-Machines, of which thefollowing is a specification.

This invention relates to spraying madelivering a spray of liquid poisonor other protecting liquid against vines.

My invention has the object to produce a simple and reliablespraying-machine of this character which permits of readily sprayingvines of varying height while the machine is in operation and whichpermits of retaining the spraying devices midway between the rows ofvines when spraying on the side of a hill.

In the accompanying drawings, consisting of three sheets, Figure 1 is avertical longitudinal section of my improved spraying-machine. Fig. 2 isa fragmentary front elevation thereof. Fig. 3 is a rear elevationthereof, showing the machine standing on level ground and the sprayerson opposite sides of the machinearranged in like positions. Fig. at is afragmentary rear elevation of the machine, on a reduced scale, showingthe sprayers on oppositesides of the machine arranged to spray both highand low vines at the same time on level ground. Fig. 5 is a similar viewshowing the position of the sprayers when the machine is used forspraying vines on the side of a hill. Fig. 6 is a top plan view of thespraying-machine on the same scale as Fig. 1 and showing the position ofthe parts when the machine is workin g on level ground. Fig. 7 is afragmentary top plan view of the spraying-machine, on a reduced scale,showing the position of the parts when the machine is used on ahillside.Fig. Sis a fragmentary top plan view showing the swiveling connectionbetween the draft-frame and the sprayersupporting shoe.

Like letters of reference refer to like parts in the several figures.

A represents the main supporting or draft frame of the cart upon whichthe spraying devices are supported, and B B are the supporting-wheelssecured to opposite ends of the axle b, which is journaled in bearings 1arranged on the frame between the front and rear cross-bars a'a thereof.

0 0 represent two shoes or supports on which the spraying devices aremounted and which are arranged lengthwise side by side underneath thedraftframe and on opposite sides of the center of the machine. Each ofthese shoes consists of a curved bar, which is dragged over the groundwith its lower rear portion and is pivotally connected with its frontportion to the draft-frame in front of the axle by a swivelingconnection, which permits the shoe to rise and fall and also to swinglaterally independent of the draftframe. This swiveling connectionconsists, preferably, of a horizontal swivel-rod d, journaled lengthwisein the front bar of the draftframe, a rocking bar 01, pivoted with itscentral portion by a vertical pivot d to the rear end of the horizontalswivel-rod and provided at its ends with horizontal pivot-pins d whichpass through eyes (1 on the arms d of the bifurcated front end of theshoe. As the supporting-shoe rises and falls in passing over the unevensurface of the ground the shoe swings vertically on the pins of therocking bar. When the cart turns or the shoe is deflected laterally, thelatter, together with the rock-bar, turns on the vertical pivot of therocking bar and by turning the swivel-rod in its bearing the shoe can betilted transversely in a vertical plane for shifting the position of thespraying devices mounted on the shoe.

E represents longitudinal rock-shafts whereby the shoes are tilted andwhich are journaled in bearings in the front and rear crossbars of thedraft-frame. Each of these rockshafts is provided in front of the frontcrossbar with an upward ly-proj ecting arm e, which is connected by alink c with an upwardlyprojecting arm 6 which is secured to the frontend of one of the swivel-rods.

F represents upright hand-levers whereby the spraying devices areadjusted and which are secured to the rear ends of the rock-shafts inthe vicinity of the operators seat G, which is mounted on the rearportion of the draftframe. Each of these hand-levers is provided with acatch f, which is adapted to engage with a segment f on the frame forholding the hand-lever and the spraying devices connected therewith inan adjusted position.

The spraying devices are mounted on the rear portion of the shoesadjacent to the seat of the operator, and each of these spraying devicesis constructed as follows:

H represents a main delivery-pipe secured upon the rear portion of theshoe and provided with two upwardly-extending branch pipes h h, whichare arranged transversely in line. The outer branch pipe h is somewhatshorter than the inner branch pipe h, and each branch pipe is providedat its upper or delivery end with a laterally or outwardly projectingspray-nozzle 7L2, which is pivotally connected with the branch pipe, sothat the nozzle can swing transversely and the direction of the spraycan be adjusted.

I represents the reservoir, which is mounted on the frame of the cartand which is filled with a liquid insecticide or other liquid suitablefor treat-in g or destroying the particular kind of insect or diseasewith which the vines are afflicted. i is a force-pump having its inletconnected with the reservoir and its outlet provided with a deliveryhose or pipe 1 which is connected by branches '6 i with thedelivery-pipes II of the spraying devices of both shoes.

When it is desired to lower the direction of the spray for sprayingshort vines or plants, each shoe is tilted so that the branch pipes leanoutwardly, and if it is desired to spray high vines or plants each shoeis tilted so that the branch pipes lean inwardly. When both rows ofvines on opposite sides of the path of the spraying-machine are ofnormal height on level ground, the branch pipes of the sprayers on bothshoes stand vertically, as shown in Fig. 3, or nearly so. If theheight-of the vines on opposite sides of the spraying-machine varies onlevel ground, either sprayer can be shifted inwardly or outwardlyindependent of the other sprayer, as shown in Fig. 4, so as to deliverthe spray against the vines at the proper point.

In order to spray vines which stand on the side of a hill and which arethe same height from the ground, one of the sprayers must be tiltedoutwardly for reaching the vines which are uphill and the other sprayermust be tilted inwardly for reaching the vines which are downhill, asrepresented in Fig. 5.

As the operator is seated adjacent to the spraying devices, he canobserve the working of the sprays and the height of the vines and canreadily shift the nozzles according to the variation in the height ofthe vines by turning the hand-levers which are within convenient reach.

WVhen spraying on level ground,the cart and the sprayers can be easilykept centrally between the two rows of Vines, but when spraying rows ofvines on the side of a hill the cart, owing to the weight of the liquidin the reservoir and the machinery, constantly slides downhill and movesforward obliquely to the line of draft, as shown in Fig. 7. Ithas beenfound in practice that by making the weight of the shoes and thespraying device's comparatively light the shoes travel substantiallyparallel with the line of draft. As the cart moves forward obliquely tothe line of draft on a hillside, that port-ion of the frame in front ofthe axle is carried upward beyond its normal position with reference tothe line of draft and that portion of the frame in rear of the axle iscarried downwardly beyond its normal position with reference to the lineof draft. It follows, therefore, that the sprayersupporting shoes, whichare pivotally connected with the frame in front of the axle, are alsocarried upwardly in the same measu re with the front part of the framewhen the cart travels obliquely on a hillside, whereby the sprayingdevices are caused to move forwardly substantially midway between thetwo rows of vines, thereby avoiding carrying one of the sprayers tooclose to the lower row of vines and the other sprayer too far away fromthe upper row of vines, which otherwise would be the case if the shoeswere pivotally connected with the draft-frame in rear of the axle. Inorder to permit the two sprayers to be held apart a certain distance andto prevent the shoes from working toward the center of the machine whenthe sprayers are tilted outwardly, the shoes are adjustably connected bya sectional connecting-bar J, the outer ends of the sections beingprovided with eyes j, which receive pivot-pins j on the rear ends of theshoes, while the inner ends of the sections lap one over the other andare connected by bolts j passing through openings formed in thesections.

If desired, a lifting contrivance may be employed for lifting the shoesfrom the ground when the machine is not in use, the means for thispurpose shown in the drawings consistin g of a transverse rock-shaft K,provided with two inner rock-arms 7a, which are connected by chains kwith the shoes, and an adjusting hand-lever K connected by a link k withan outer rock-arm k on the transverse rock-shaft.

My improved spraying-machine is very compact, which permits of sprayingvines which are arranged close together.

I claim as my invention- 1. In a spraying-machine, the combination withthe draft-frame provided with supporting-wheels, of a supporting-shoeadapted to trail on the ground and pivotally connected at its front endwith the draft-frame in front of the axis of the wheels and a sprayingdevice mounted on the rear portion of the supporting-shoe, substantiallyas set forth.
